Accelerator Plus documentation is available in HTML and PDF format.
Accelerator Plus has two main commands, wx and wxmgr.
To set up your user shell with Accelerator Plus you need to know where the Altair Accelerator software has been installed.
This section summarizes how to submit and run a job.
There may be multiple instances of Accelerator Plus running at a given site. You choose which one to use with the variable NC_QUEUE, which by the way is the same variable also used to select the instance of Accelerator.
This chapter provides examples of submitting jobs using CLI (command line interface) commands.
Using an array provides the option of submitting multiple jobs in a specific order.
Setting the environment is critical for correct job execution. Accelerator provides two methods to control the execution environment.
When a job is being submitted, a pre-condition and/or a post-condition can be specified.
While Accelerator Plus supports the use of FairShare groups, their utility depends upon the underlying batch system.
Job submission can be affected by the value of the optional variables NC_RUN_ARGS and NC_RUN_ARGS, which specify a list of arguments that are pre-pended and appended to the argument list passed to the submission command.
The scheduling priority affects the order in which the jobs are scheduled. The range is 1 to 15.
Accelerator Plus provides several commands of job controls, including wait, stop, cleaning and debugging.
On occasion, jobs that run successfully outside of Accelerator Plus fail when run through Accelerator Plus. When this occurs, mostly likely the setups are not the same: the environment, inputs or other parameters may be different, a misconfiguration or there is a problem with NFS.
This document is intended for those who have been using the Platform LSF batch system and are now moving to using Accelerator Plus on top of the LSF batch system.
This guide is written for the Accelerator Plus system administrator who needs to configure and manage one or more Accelerator Plus instances.
